<li>Structurally, Square’s NAV trade still works. The Hynix stake alone implies a 60%+ discount, well above local norms, with policy tailwinds supporting long-term compression.</li>
<li>Near term, Square’s NAV is a derivative of retail Hynix flows. Today was the first real unwind since the 10th, with retail net selling roughly 5x yesterday’s retail net-sell.</li>
<li>Retail sold both, but Hynix again dominated the tape. Retail is range-trading ₩500ks, and that behavior is the key driver of Square’s short-term NAV inflection.</li>
